More boring health research . . . however, it may be of potential benefit to those who take an interest in food (and/or supplements) as medicine, while improving the benefits of medication. (footnoted with online links)
"Quercetin is an antioxidant flavonol found naturally in foods such as apples, plums, red grapes, green tea, elder flower and onions, just to name a few."
Quercetin May Be a Useful Supplement for Many
"In another study funded by the U.S. Defense Advanced Research Projects Agency (DARPA), published in 2008, animals treated with quercetin were challenged with a highly pathogenic H1N1 influenza virus. Again, the treatment group had significantly lower morbidity and mortality than the placebo group."
"Story at-a-glance
Quercetin has been shown to combat inflammation and acts as a natural antihistamine. Several studies have highlighted quercetin’s ability to prevent and treat both the common cold and influenza
Another, less known benefit and use for quercetin includes the prevention and/or treatment of high blood pressure, cardiovascular disease, metabolic syndrome, certain cancers, gout, arthritis and mood disorders
A review of quercetin’s effect on metabolic syndrome found it significantly reduced fasting plasma glucose when taken for at least eight weeks at a dosage of 500 milligrams per day or more
Other recent research found quercetin has a beneficial impact on nonalcoholic fatty liver disease by ameliorating inflammation, oxidative stress and lipid metabolism
Quercetin also has the ability to trigger tumor regression by interacting with your DNA and activating the mitochondrial pathway of apoptosis (the programmed cell death of damaged cells)"
